Concurrent multipath transfer in Fi-Wi access networks

Fiber-Wireless Access Networks (Fi-Wi) shows a promising future owing to the cost effective, high bandwidth and ubiquity features. Previous studies have addressed network layers to provide high data rates and lower delays to enhance the overall network quality without taking into consideration the end user QoS. In order to provide high QoS, transport layer services needs investigation as they work on end to end principle. Stream control transmission protocol (SCTP) is a new transport layer protocol with novel services that can help Fi-Wi access network to enhance the individual end user QoS. In this work, we investigate the usage of concurrent multi-path transfer (CMT) with stream control transmission protocol (SCTP) for Fi-Wi Access Networks. The use of SCTP in Fi-Wi Access network provides bandwidth aggregation, redundancy and resilience to the network. The simulation results show a significant performance gain in terms of throughput when compared with TCP new Reno, a widely used transport layer protocol.
